I just purchased it and it's not a bad app. With a little work it could be a great app. Was shocked to see you couldn't enter your own text.
Similar to what other have said. let you have files of your own text. The common words are NOT the common QSO words. hw abt wx, rig, dipole, rig names, beam, spy, hw?, tnx, etc. w5mmt / hs0zac
This is a great idea! Abbreviations are very common in qso's and being able to practice them would be a great asset.
